What is the actual symptom you see if you don't do that?

If a plug-in uses threads and httpd is bound (?) to some dummy thread
routines in libc, doesn't that screw up the plug-in or confuse libpthread?

Emperical results show that as long as httpd doesn't bind to dummy
thread routines in libc the plug-in's use of threads is fine.
